Syriza’s UK spokesperson Marina Prentoulis told the BBC this morning that the the International Monetary Fund paper has raised serious questions over the European lenders' deal:

On debt sustainability:

We had a report from the IMF a few days ago saying the debt was unsustainable. The three institutions, the troika, have brought Greece to this situation.

From the last few months tsipras was saying the debt should be restructured. The partners say they do not want to discuss the debt. But we know that it is urgent that somebody takes of it.

On the IMF:

We have to remember that the IMF will be part of the measures and have to agree to the reforms. We see a split between the IMF and the EU.

On the rest of Europe:

I hope the European people see what big games the European Commission has been playing, what lies they have been telling. These measures that we were blackmailed to take are not working - the same goes for the debt. All the countries of the EU are in debt. We must prepare measures to reconsider all of that debt.

Protesters from the All Workers Militant Front (PAME) a communist trade group, have occupied the Ministry of Macedonia and Northern Greece, a government department based in Thessaloniki, in protest over the new austerity measures agreed on in the bailout.

The schedule for today in the Greek parliament:

10am (8am BST): debate on the Brussels bill in four consecutive parliamentary committees - Finance, Social Affairs, Production & Trade and Civil Service.

2pm (12noon BST): End debate, send vote to plenary so that it can be voted on by midnight.

The European Commission has said it use a controversial European Union fund called the European Financial Stability Mechanism to lend Greece €7 billion in short-term financing, against the wishes of European nations that do not use the euro, such as the UK.

A proposal leaked to Reuters said the loan would only be for three months, until a third bailout package from the eurozone is agreed.

My colleague Matt Dathan has some more information on David Cameron backing the IMF call for Greek debt relief.

In Prime Minister's Questions, Cameron stressed the EU needs to come up with an idea for managing Greece's debt that is sustainable in the long-term.

He insisted that "we all feel for the Greek people".His spokeswoman was keen to stress:

British taxpayers' money shouldn't be put on the line for a eurozone bailout.We're very clear about that and we're confident we can deliver that.

However: the voting mechanism means that Cameron does not have the ability to block taxpayers' money going to Greece.

The system is called QMV: Qualified Majority Vote. Here's Matt on how it works:

Instead of giving all 28 countries the ability to block any measure they don't like, which would end up in deadlock on loads of issues, it means that measures can be approved even if only a proportion of the countries vote for it. It's called 'qualified majority' because it takes into consideration the population of each country when working how much sway they get in the vote.

In some respects Cameron and Osborne have already backtracked on their commitment not to use UK funds. The UK Treasury approved the use of EFSM funds earlier as long as the UK is protected by guarantees.

Foreign developments, in particular, pose some risks to U.S. growth. Most notably, although the recovery in the euro area appears to have gained a firmer footing, the situation in Greece remains difficult. And China continues to grapple with the challenges posed by high debt, weak property markets, and volatile financial conditions.

We won't hear the results of the Greek parliamentary vote until 10pm tonight.

There's a Eurogroup teleconference at 10am on Thursday to judge whether Greece has passed the four measures needed to start bailout talks, plus the short-term financing needed to stop it going bust before the bailout is secured.
